The Fermi GBM team reports the detection of a likely LONG GRB
At 14:16:56 UT on 14 Jul 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260714A (trigger 805731421.523672 / 260714595).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 59.3, Dec = 14.1 (J2000 degrees, equivalent to J2000 03h 57m, 14d 05'), with a statistical uncertainty of 3.5 degrees.
The angle from the Fermi LAT boresight is 67.0 degrees.
